From looking at the site, I gather you're doing photo hosting, but that's about all I gather. What I think you should be thinking about is "How am I different than flickr?" As far as I can see, none of the "other features" differentiates your site from flickr. So why would someone go for your service instead of a trusted site with a huge network effect?

And as another poster said, you shouldn't brag about stuff that's little more than basic functionality. Sorting by date is not a cutting-edge feature. Neither is not spamming the user's friends. Or "easy access to full size." Listing those sorts of things as features makes it look like you have so few real features that you had to stretch to fill out your list.

Finally, you need to figure out what your audience is. It's extremely unlikely that you're going to beat Flickr at their own game, so you need to find a niche they aren't serving well. Frankly, I'm having trouble seeing what that niche would be, but if you want to succeed you're going to have to find it.
